Transmetallic biomimetic Hydrogel implants restore osteogenesis-angiogenesis coupling via Fe/Co ionic microenvironment remodeling for enhancing osteoporotic fracture healing
The regeneration of osteoporotic bone fractures remains a significant clinical challenge, primarily due to the iron overload-induced functional impairment in osteoporosis-angiogenesis coupling. Here, we developed a transmetallic biomimetic hydrogel implant (TBH) to address this issue. The TBH was fabricated by crosslin...
